BACKGROUND New preventive strategies against the development of allergic diseases focus on potentially immunomodulatory components, such as bacterial LPSs. Optimal time frames for initiating immunomodulation to receive a sufficient effect against allergen sensitization are still unclear. OBJECTIVE Using a mouse model, we investigated the influence of(More)
We have previously shown that Th2-polarized airway inflammation facilitates sensitization towards new, protein antigens. In this context, we could demonstrate that IL-4 needs to act on cells of the hematopoetic and the structural compartment in order to facilitate sensitization towards new antigens. We thus aimed to elucidate possible mechanisms of action(More)
The study compares altered states of consciousness induced by the hallucinogens (--)delta9-trans-Tetrahydrocannabinol (delta9-THC) and N,N-Dimethyltryptamine (DMT) using two placebo control groups. A total of 24 subjects received 250 mug delta9-THC p.o./kg body weight and 26 subjects were treated with 250 mug DMT i.m./kg. Placebo was given to 24 subjects.(More)
the literature dealing with structural aberrations of the Y chromosome and their phenotypic effects is reviewed. A new observation of a patient with Turner's syndrome and the karyotype 45,X/46,X,i(Yp) reported here allows some conclusions on the problem of the localization of sex-determining factors on the Y chromosome. The comparative analysis of all these(More)
X-linked recessive anhidrotic ectodermal dysplasia with immunodeficiency is a developmental and immunologic disorder caused by mutations in nuclear factor-kappaB essential modulator (NEMO), which is essential for nuclear factor-kappaB activation. Early in life, affected boys present a typical appearance, with hypotrichosis or atrichosis, hypohidrosis or(More)
Two different double-blind trials with Δ9-Tetrahydrocannabinol were performed on altogether 73 normal volunteers. Factoranalyses yielded the following three dimensions of the Δ9-THC experience: a) “derealization of self and surroundings”, b) “anxious-depressive state” and c) “euphoric-stimulated state”. “derealization of self and surroundings”,(More)
RATIONALE Hereditary pulmonary alveolar proteinosis (hPAP) caused by granulocyte-macrophage colony-stimulating factor (GM-CSF) receptor α-chain (CSF2RA) deficiency is a rare, life-threatening lung disease characterized by accumulation of proteins and phospholipids in the alveolar spaces. The disease is caused by a functional insufficiency of alveolar(More)
BACKGROUND The hygiene hypothesis negatively correlates the microbial burden of the environment with the prevalence of T helper type 2 (Th2)-related disorders, e.g. allergy and asthma. This is explained by Th1 triggering through pathogen-associated molecular patterns via Toll-like receptors (TLRs). In this study, the biological effects of a TLR2/6 agonist(More)
Renal ischemia-reperfusion contributes to reduced renal allograft survival. The peptide Bβ(15-42), a breakdown product of fibrin, attenuates inflammation induced by ischemia-reperfusion in the heart by competitively blocking the binding of leukocytes to endothelial VE-cadherin, but whether it could improve outcomes in renal transplantation is unknown. Here,(More)
BACKGROUND Histamine drives pruritus in allergic skin diseases which clinically constitutes a most disruptive symptom. Skin pathology in allergic skin diseases is crucially influenced by different T-helper subsets. However, the contribution of different histamine-receptors to T-helper cell dependent skin pathology has not been definitively answered. Models(More)
